Martin Keown says Mesut Ozil needs to show the same levels of commitment as Alexis Sanchez

“Sanchez is the leading goal scorer in the Premier League but he presses so well and we’ve seen him do it for his national team.

“Hopefully Ozil can tap into it. If Arsenal do that then they will win the ball back high up the pitch and put Bayern’s defence under pressure.

“(Mats) Hummels is an outstanding central defender but you can test him if you win the ball. But Sanchez needs support from his team-mates.”

Former Real Madrid star Ozil was slated for his performance in the recent 3-1 defeat at Chelsea, allowing Nemanja Matic time and space on the ball as Arsenal saw their title challenge effectively ended.

Keown added: "Arsenal slipped up against Watford and then went into the Chelsea without any momentum. Sanchez and Ozil barely got a kick. Now it's about bouncing back. You can't just take your ball, pack up and go home.

"To be fair to Arsenal, they have readjusted well in the past. You fight all season to get into the Champions League so why not make something happen when you are there.

"They should be inspired by the competition to dig out something extra and try and get that all important away goal.

"Why not dare to dream? But it has to be an outstanding performance.

"Arsenal are capable of getting a draw or being just the odd goal behind.

"It would be a monumental result. Then that will set up one of the greatest nights at the Emirates in this competition."

Arsenal will have to deal with the likes of Douglas Costa and Arjen Robben tonight

But just how do Arsenal's defence stop Bayern's potent attacking threat of Robert Lewandowski, Arjen Robben and Douglas Costa?

Keown, part of the Gunners' Invincible side and who faced the likes of Gabriel Batistuta and Patrick Kluivert during his playing days in the Champions League, said: "You have to be able to deal with Bayern's wide players.

"They are are as direct as I have seen and have so many options. (Franck) Ribery sat out for a while, Costa has bags of pace, Robben has been lethal in front of goal, he hasn't lost any of his quality, pace or sharpness.

Laurent Koscielny and Arsene Wenger know just how tough Bayern Munich are to beat

"But they always find inspirational moments to score goals at the right time.

"Carlo Ancelotti has won the Champions League three times as a manager and he knows how to get the job done in this tournament so it's a difficult combination for Arsenal.

"Pep Guardiola has gone and it would be ironic if Bayern were to go on and win it. This group of players have won everything yet they still have the hunger.

"But Arsenal may see this as a welcome change to the Premier League. They have a fighting chance."
